There is one clinical trial.
The pathophysiology of the most common corneal endothelial dystrophies (Fuchs' Corneal Endothelial Dystrophy (FECD)) is beginning to be dismembered. One of the most common genetic anomalies is a triplet repetition in one of the introns of the Transcription Factor 4 (TCF4) gene located on chromosome 18. However, the number of repetitions varies greatly from one patient to another.
Analysis number of CTG triplet repetitions in the intron of the Transcription Factor 4 (TCF4) gene.. Mutation rs613872.
Analysis frequency of the mutation rs613872 in the intron of the Transcription Factor 4 (TCF4) gene..
Description: Correlation between visual acuity measured before noon eye by eye of ETDRS scale (international standardized Early Treatment Diabetic Retinopathy Study scale) results and number of CTG triplet repetitions in the intron of the Transcription Factor 4 (TCF4) gene.
Measure: Visual acuity Time: Year: 0 and 1Description: Analysis number of CTG triplet repetitions in the intron of the Transcription Factor 4 (TCF4) gene.
Measure: CTG triplet repetitions in the intron of the Transcription Factor 4 (TCF4) gene Time: Year: 0 and 1Description: Analysis frequency of the mutation rs613872 in the intron of the Transcription Factor 4 (TCF4) gene.
Measure: Mutation rs613872 Time: Year: 0 and 1Description: Analysis frequency of the other mutation type nucleotide polymorphisms in the intron of the Transcription Factor 4 (TCF4) gene.
Measure: Other mutation Time: Year: 0 and 1Description: Analysis refraction with the auto-refractor tonometry non-contact air.
Measure: Refraction with the auto-refractor tonometry Time: Year: 0 and 1Description: Correlation between visual acuity measured before noon eye by eye on the ETDRS scale (Early Treatment Diabetic Retinopathy Study scale) in a controlled glare situation. ETDRS (Early Treatment Diabetic Retinopathy Study) scale will be allowed to measure visual acuity uses an eye chart with 5 letters per line. The scores range from 0 (no letters read correctly) to 100 (all letters read correctly).
Measure: ETDRS scale (Early Treatment Diabetic Retinopathy Study scale) in a controlled glare situation Time: Year: 0 and 1Description: Correlation between interferometry, tear meniscus height, Non Invasive Break-Up Time (NIBUT) and meibography results.
Measure: interferometry, tear meniscus height, Non Invasive Break-Up Time (NIBUT) and meibography Time: Year: 0 and 1Description: Comparison corneal thickness in Optical Coherence Tomography (OCT).
Measure: Corneal thickness in Optical Coherence Tomography (OCT) Time: Year: 0 and 1Description: Comparison reflectivity results measure by Optical Coherence Tomography (OCT). Optical Coherence Tomography (OCT) is an imaging technique, which is able to produce, in vivo, cross-sectional images of lesions.
Measure: Reflectivity results measure by Optical Coherence Tomography (OCT) Time: Year: 0 and 1
